| 34 | <p>The <b><font face="Courier New">rnd</font></b> function returns a (pseudo) random number less than 1 but greater or equal to 0. The random number generator is initialized by means of an |
| 35 | optional seed value. Afterwards, if no new seed is provided, the last generated number will be used as seed for the next random number. Without a previous initialization a value calculated from the |
| 36 | system time will be used as seed value when <b><font face="Courier New">rnd</font></b> is used the first time. |

| 62 | <p><font face="Courier New"> var float v_veeletlen := rnd( 1.9 ); </font></p> |
| 63 | <p>The variable v_veeletlen will have a random initial value between 0 and 1. The argument of the function is an optional seed value used for the first time random value calculation. If it is |
| 64 | omitted, the system time will be used as seed. |
